Trail Mix, actually that is lunch when working outside. Buy ready-made stuff, then mix it with equal parts wallnuts, and almonds…sometimes pacans too.

Been eating granola bars too (store brands are better than name brands) more convenient, and they don’t go stale. Keep a bunch in the glove compartment. Jerky is too salty.

I have bad memories of squished hot PB &
